Analysis of Different PWM Techniques for Enhanced Ultrahigh Gain Z‐Network Topology
International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.In these modern times, the Z‐source inverters (ZSIs) have become a revolutionary invention ever since the year 2002. The pulse‐width modulation (PWM) technique used for most of the ZSIs is simple boost control PWM (SBC‐PWM), and the SBC‐PWM implies for a greater voltage stress on the inverter bridge and provides less boost factor.
